Patent GB-786048-A (GB)
IPC: G11B5/004
Abstract: 786,048. Digital electric calculating-apparatus. DIRKS, G. June 23, 1950 [Oct. 1, 1948], No. 37230/54. Divided out of 786,021. Drawings to Specification. Class 106 (1). An electric calculator having a one-denomination arithmetic unit with input means and output means, comprises a magnetizable storage surface bearing a plurality of number areas, at least one of which is accessible to the arithmetic unit while the others are not, and means for selectively transferring a number from any of the non-accessible areas to an accessible area; computing elements in the arithmetic device may be influenced jointly by two or more signals representing digits in the same denomination of two numbers, one being received from an accessible area of the storage and another from the input means, the joint influence generating a result signal in the output means representative of a computation of the digits in that denomination. The detailed description is the same as part of the description in Specification 786,021, but the claims differ. Specifications 786,022, [Group XVI], 786,026, 786,027, [Group XVI], 786,033, 786,034, 786,041, 786,044, 786,047 and 786,050 also are referred to.
Patent GB-2035464-A (GB)
Title: Actuator protection assemblies
IPC: F15B11/048
Filed: 1979-03-19
Abstract: Existing actuator protection assemblies prevent piston damage by using a relief valve to provide a constant resistive force at the end of the piston's travel. This tends to lead to a complicated and expensive design. In the present invention a change in the fluid supply is used to decelerate the piston at the end of its stroke. In the illustrated embodiment, a servovalve 5 for piston 1 is controlled by a control system 15 actuated by two sensors 7, 8 which are arranged to sense when the piston is nearing the end of its stroke. <IMAGE>

Patent GB-2031657-A (GB)
Title: Steep gradient static characteristics electrical transformer
IPC: H01F27/28
Filed: 1979-09-13
Abstract: In an electrical transformer the primary and secondary coils 2, 3 each comprise a conductive band substantially as wide as the coil. Each primary coil is mounted on the same magnetic core column as one or more secondary coils so that the primary and secondary coils are coaxial and face one another with a gap between them. At high currents the current through the coils tends to shift to the outer (non-adjacent) edges of the conductor bands, and the gap encourages dispersed flux 6 which does not link both coils. These factors increase the slope of the output characteristic such that the short circuit current can be only twice the operating current. <IMAGE>

Title: Garnet Film for a Magnetic Bubble Device
IPC: H01F10/24
Filed: 1979-10-12
Abstract: A garnet film for a magnetic bubble device has the formula  R<I>3-xRx<II>Fe5-yAlyO12 where R<I> is at least one of Y, Gd, Yb, Tm, Lu and La, R<II> is at least one of Sm and Eu, 0.5<x<2.0 and 0.2<y<0.9, with the proviso that if Gd is present as some or all of R<I> then the amount of Gd is not greater than 0.5 mol per molecular formula. Such a film can produce a device with bubbles having a diameter of not greater than 1.5  mu m because the saturation induction may be kept at a low level without excessive reduction in the Curie point.
